Abstract Contrast-enhanced harmonic endoscopic ultrasonography (CH-EUS) with contrast agent enabled us to assess the hemodynamics closely, despite limited data in pancreatic tumors. We have initiated a prospective, single arm, and non-randomized study to clarify the accuracy and safety of CH-EUS with Sonazoid and time-intensity curve (TIC) analysis for diagnosing benign or malignant pancreatic tumors. A total of 200 patients will undergo CH-EUS and TIC analysis. Receiver operating characteristic (ROC) analysis will be used to determine the optimal parameter cutoff values for TIC analysis. This will clarify whether CH-EUS and TIC can further improve the diagnosis of pancreatic tumors over conventional EUS.

Abstract Recently, endoscopic ultrasonography (EUS)-guided ethanol ablation for small pancreatic neuroendocrine tumors (p-NETs) has been reported. However, the efficacy and safety of the technique remain unclear. We have launched a prospective pilot study of EUS-guided ethanol ablation for p-NETs. The major eligibility criteria are the presence of a pathologically diagnosed grade (G) 1 or G2 p-NET, a tumor size of 2cm, and being a poor candidate for surgery. A total of 5 patients will be treated. The primary endpoint will be the complete ablation rate at 1 month after treatment.

Abstract A 45-year-old female who presented with loss of consciousness and a cold sweat was found to have a pancreatic tumor and multiple liver metastases. Laboratory studies showed marked hypoglycemia and inappropriately elevated serum insulin, C-peptide, and serum tumor markers. Fine needle aspiration revealed Grade 3 small-cell type primary pancreatic neuroendocrine carcinoma. Consequently, the diagnosis of malignant insulinoma was made. Transarterial embolization (TAE) for hepatic metastases resulted in the reduction of tumor volume and prompt resolution of hypoglycemic attacks, whereas diazoxide and systemic chemotherapy had been ineffective for controlling blood glucose levels, and octreotide was unavailable due to the allergic effect. This case report highlights the potential usefulness of TAE for malignant insulinomas in the management of hypoglycemia.
